Ages in Chaos
Ages in Chaos is a book by the controversial writer Immanuel Velikovsky, first published by Doubleday in 1952, which put forward a major revision of the history of the Ancient Near East, claiming that the histories of Ancient Egypt and Ancient Israel are five centuries out of step. He followed this with a number of other works where he attempted to complete his reconstruction of ancient history, collectively known as the Ages in Chaos series.
Velikovsky's work has been harshly criticised, including even by some fellow chronological revisionists.
Velikovsky had put forward his ideas briefly in Theses for the Reconstruction of Ancient History in 1945, where he claimed that the history of the ancient Near East down to the time of Alexander the Great is garbled, but Ages in Chaos was his first full-length work on the subject.
His starting point for the first volume of the series was that the Exodus took place not, as orthodoxy has it, at some point during the Egyptian New Kingdom, but at the fall of the Middle Kingdom.  In this and later volumes, he made heavy use of the concept of "ghost doubles" or alter-egos: historical figures who were known by different names in two different sources (e.g. Egyptian and Greek) and were considered to be entirely different people living in different centuries, but who he proposed to be actually erroneously dated accounts of the same individuals and events.
First he claimed that the Ipuwer Papyrus came from the beginning of Egypt's Second Intermediate Period, and that this was an Egyptian account of the Plagues of Egypt. He then identified Tutimaios as the Pharaoh of the Exodus (much earlier than any of the mainstream candidates), the Hyksos with the biblical Amalekites, the Egyptian Pharaoh Hatshepsut with the Biblical Queen of Sheba, the land of Punt with Solomon's kingdom, and Pharaoh Thutmose III with the Biblical King Shishak. He claimed that the Egyptian Amarna letters from the late 18th Dynasty describe events from the kingdoms of Israel and Judah, from roughly the time of King Ahab.
Later works on ancient history
A second volume was due for publication shortly after this but was postponed. Instead it was followed in 1960 by Oedipus and Akhnaton, where he claimed that the story of the Pharaoh Akhenaten was the origin of the Greek legend of Oedipus, and that Amenophis III was Laius, and Tutankhamun was Eteocles. 
In the last two years of his life Velikovsky published a further two volumes of the series. In Peoples of the Sea he dealt with the final period of his reconstruction, the Persian invasions of Egypt. Manetho's 20th dynasty here becomes identified with the dynasties which ruled a newly independent Egypt in the early 4th century BCE, and Nectanebo I is a ghost double of Rameses III.  Rameses III fought invasions by the Sea Peoples, including the "Peleset", conventionally identified with the Philistines. According to Velikovsky, the "Peleset" are actually the Persians and the other Sea Peoples are their Greek mercenaries. The 21st dynasty then becomes a line of priest-kings who ruled in the oases simultaneously with the Persians.
In Ramses II and His Time Velikovsky identified each of the major 19th dynasty pharaohs with a corresponding pharaoh of the 26th dynasty. Thus, Ramses I was an alter-ego of Necho I, Seti I of Psamtik I, Ramses II of Necho II, and Merneptah of Apries. In order to make these identifications work, Velikovsky claimed that the Hittite Empire was an invention of modern historians, and the supposedly Hittite archaeological remains in modern Turkey were actually Chaldean, i.e. Neo-Babylonian. The Hittite kings are held to be ghost doubles of the Neo-Babylonian kings, and Rameses II's battle with the Hittites at Kadesh is identical to Necho's fight against Nebuchadrezzar II at Carchemish, Nabopolassar is Mursili II, Neriglissar is Muwatalli, Labashi-Marduk is Urhi-Teshup, and Nebuchadrezzar II is Hattusili III. 
At the time of his death he considered that completing his reconstruction of ancient history would require a further two volumes: The Assyrian Conquest and The Dark Age of Greece; these were never published in print in English, but online versions are available at the Velikovsky archive. In the former work, Velikovsky separated the 18th and 19th dynasties, specifically arguing that over a century separated Ay and Horemheb, conventionally regarded as his successor. Instead, he had the 22nd through 25th dynasties follow upon the earlier part of the 18th, leading down to the Assyrian invasions of the early 7th century BCE. The "great king" who crowned Horemheb was the Assyrian king.
Controversy and criticism
The revised chronology proposed by Ages in Chaos has been rejected by nearly all mainstream historians and Egyptologists. It was claimed, starting with early reviewers, that Velikovsky's usage of material for proof is often very selective. In 1965 the leading cuneiformist Abraham Sachs, in a forum at Brown University, discredited Velikovsky's use of Mesopotamian cuneiform sources. Velikovsky was never able to refute Sachs' attack.
In 1984 fringe science expert Henry H. Bauer wrote Beyond Velikovsky: The History of a Public Controversy, which Time described as "the definitive treatise debunking Immanuel Velikovsky". Bauer accused Velikovsky of dogmatically asserting his own point of view to be correct, where at best this is only one possible interpretation of the historical material in question, and gives several examples from Ages in Chaos.
In 1984 Egyptologist David Lorton produced a detailed critique of chapter 3 of Ages in Chaos, which identifies Hatshepsut with the Queen of Sheba, e.g. accusing Velikovsky of mistakes which he would have avoided if he had a basic knowledge of the languages of the ancient near east. 
In 1978, following the much-postponed publication of further volumes in Velikovsky's Ages in Chaos series, the United Kingdom-based Society for Interdisciplinary Studies organised a conference in Glasgow specifically to debate the revised chronology. The ultimate conclusion of this work, by scholars including Peter James, John Bimson, Geoffrey Gammonn, and David Rohl, was that this particular revision of chronology was untenable, although they considered that the work had highlighted problems with the orthodox chronology. 
David Rohl, one of those involved in the 1978 Glasgow conference, has developed his own revised chronology. While he agrees that the Exodus should be dated to the collapse of the Middle Kingdom, and that Tutimaios is the Pharaoh of the Exodus, there are few points of contact between the Velikovsky and Rohl chronologies, largely because of the different methodologies used to resolve the later periods.
James, another Glasgow delegate who went on to publish a work challenging the concept of a widespread dark age at the end of the Bronze Age, credited Velikovsky with "point[ing] the way to a solution by challenging Egyptian chronology", but criticised Velikovsky's chronology as "disastrously extreme", producing "a rash of new problems far more severe than those it hoped to solve" and noted that "Velikovsky understood little of archaeology and nothing of stratigraphy". 
One important disagreement is that Rohl and James consider that the chronology of the ancient Near East becomes fixed by the conquests of the Assyrians in the 7th century BCE. Velikovsky carried his revisionism into the Late Period of ancient Egypt, and considered that chronology only becomes fixed by the conquests of Alexander the Great in the 4th century BCE. They have also rejected some of Velikovsky's more extreme claims e.g. non-existence of Hittite Empire, changing the order of some Egyptian dynasties. Rohl and James's views remain controversial and are not accepted by most historians.

"Velikovsky confronted a panel of four professors [at Brown University on March 15, 1965]: Leon N. Cooper (physics), Bruno J Giletti (geology), Charles Smiley (astronomy) and Abraham J. Sachs (history of mathematics) [who was substituting for Otto Neugebauer ], moderated by Henry Kucera (linguistics). In the event, Velikovsky debated the first three handily. He was stunned by Sachs whose address was both a rhetorical and substantive tour de force. Velikovsky's rebuttal began: 'Dr. Sachs threw so many accusations in that Philippic of his that I am at a difficulty to answer; but I invite Dr. Sachs to spend the hour and a half tomorrow at the meeting [at Diman House], and every one of you too, and point by point each of his statements will be proven wrong.' Unfortunately, Sachs did not show up the next day and Velikovsky did not even mention Sachs [according to the tape recording of the proceedings in the possession of Warner B. Sizemore who loaned it to Ellenberger March 31, 1979]. Curiously, Velikovsky's file for the Brown trip contains typed rebuttals to all the panelists except Sachs, for whom only partial, penciled notes exist—but later that year Velikovsky would reply to Kim J. Masters, a Princeton sophomore, within a week in The Daily Princetonian (Nov. 15, 1965) over a criticism of Oedipus and Akhnaton. Velikovsky's rebuttal to Masters was scathing, running the gamut from haggling over details to ad hominems.
